Conical Ostry volcano, its slopes partially mantled by glaciers, is a late-Quaternary stratovolcano that rises to 2552 m, forming one of the highest peaks of the northern Sredinny Range. Ostry, also known as Ostraya, is located on the western side of the major NE-trending graben along the axis of the northern Sredinny Range. An unnamed 2127-m-high cinder cone on the SW flank of Ostry, informally referred to as "Cone X," erupted about 4000 years ago, producing a basaltic lava flow.

The peak at the center of this NASA Landsat image (with north to the top) is Ostry. This late-Quaternary stratovolcano, whose name means "Sharp Peak," rises to 2552 m, forming one of the highest peaks of the northern Sredinny Range. Ostry lies WSW of the broad glacier-covered Snegovoy volcano (upper right). The smaller Kutina stratovolcano (bottom-center) is located immediately to the south of Ostry.

Snow-capped, conical Ostry volcano, seen here from the NW, rises to 2552 m. Ostry, whose name means "Sharp Peak," forms one of the highest peaks of the northern Sredinny Range. On the right horizon is an unnamed 2127-m-high cone on the SW flank of Ostry, informally referred to as "Cone X," which erupted about 4000 years ago, producing a basaltic lava flow.

Three volcanoes in the northern Sredinny Range rise above the clouds in this helicopter view from the south. Spokoiny volcano is in the foreground, with snow-covered 2552-m-high Ostry (Ostraya) volcano, one of the highest volcanoes in the northern Sredinny Range, in the background. The rounded volcano on the west (left) flank of Ostry is an unnamed cone that was active during the Holocene.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
